How to Read Gauge Numbers
- 2×4: two needles 2 mm apart, 4 mm width (4-thread overlock).
- 3×4, 3×5, 5×5: gap between chain needle and overlock needle, then overlock width (5-thread).
- 3×5.6, 3×6.4: three needles over 5.6 or 6.4 mm (flatlock).
- R40, B56: gauge inside a Pegasus number (4.0 mm, 5.6 mm).
The needle plate, feed dog, presser foot and needle clamp must share one gauge. Otherwise, the needle can hit the plate and break.
How to Find Your Needle Plate and Feed Dog Number
- Read the machine label. Note the full model code, like E4S-4-M03/333 or W562-01CB. The last part shows version and gauge.
- Read the old plate. Most genuine plates have the number stamped underneath.
- Search it above. Type either number; “=” means both numbers are the same part.
- Count and measure. If the number is worn off, count the needle holes and measure across them.
Signs of wear: uneven feeding, puckering, the needle hitting the plate, thread breaking at the slot, or flat feed dog teeth. See our maintenance checklist.
Needle Plate and Feed Dog FAQ
Which needle plate fits the Siruba 747?
The standard Siruba 747 uses the E809 plate with the H445 / D575 feed dog set. The 747K uses E229 with H204 / D210.
Are JACK E4 and Pegasus EX needle plates the same?
Yes. JACK 121215004 is the same 2×4 plate as Pegasus 277505R40, and JACK 20715008 is the same 5-thread plate as Pegasus 277517R40.
Which needle plate fits the JACK W4 flatlock?
For the standard W4 (01GB), use JACK 30115067, the same as Pegasus 257018B56 (3×5.6). For 6.4 mm, the JACK number is 30115068.

Can I use a 4-thread needle plate on a 5-thread machine?
No. A 5-thread plate has an extra slot for the chain needle, so the slots and gauge are different.
